I bought a few months ago the wiper. As such he is doing what he should. Refilling is super easy due to the removable tank. Spray width slightly irregular and rather thin, but that does not detract from the whole. Leaving aside the wiper but longer and are generally, he empties (despite what appears empty tank) automatically via the nozzle on the floor. Property me so messed up the wooden floor. The things you should have somewhere so stand on a tarp, always check the tank and drain it well, or otherwise ensure that the floor is spared.
